Last Tango dress, aqua, hand washable,S

This great dress is by Last Tango in size small. It has an inside dress, with an outer top. The tag is worn, so it’s hard to tell what fabrics it is made of. My guess would be polyester and spandex. It is in very good condition, lightly worn. Pit to pit measurement is 17 inches. The length is 34 inches. This is an unusual dress!
